Abstract
Description
- This application claims priority under 35 U.S.C. §119 to Brazilian patent application No. 1,101,583-7, filed Apr. 6, 2011, which is hereby incorporated by reference in its entirety.
- 1. Field of the Invention
- The present invention refers to the field of recycling of used cooking oils in general, and to recycling of used cooking oils by means of their processing together with a pod including substances of the wax type and similar, in particular.
- 2. Background of the Invention
- Considering current consumption patterns of cooking oils and the serious environmental consequences often associated with their disposal, there is a significant economic and environmental value associated with the possibility of their recycling in general, and of their valorization at the point of consumption, in particular.
- In fact, such valorization directly at the point of consumption presents several advantages, notably because it avoids the logistic required for collecting used cooking oils to a central recycling or disposal location, and because it represents an additional source of economic value, allowing consumers to use a basic material for obtaining other materials or products for other uses and benefits.
- However, processes for recycling used cooking oils in a domestic, or small scale commercial setting, whether this is that of a household or that of a restaurant, are conditioned by several technical and functional constraints. It is therefore particularly important that a process for recycling used cooking oils in such settings presents a set of characteristics, notably in terms of easy use (in particular, simple handling of raw materials involved) and in terms of general efficiency (in particular, obtaining the intended quality with the least energy use by the process).
- In the scope of the present document, the expression “used cooking oils” refers to oils used in food in general, independently of their origin or production, for dressing or cooking, such as for example frying, or other uses, whereby oils are used or exceed their use deadline, and loose food grade value, being therefore available and suitable for recycling or final disposal. Within the meaning of the expression “used cooking oils” are further considered food oils in the liquid or solid state, as well as other substances of the fat type presenting characteristics similar to food oils.
- 3. Description of Related Art
- The concept of processing used cooking oils together with a processing pod, as well as a machine specific for such purpose, has been disclosed by the author and is therefore known in the related art.
- In fact, the author has previously researched and developed the concept of recycling used cooking oils into candles, by means of their processing together with a composition of solidifying substances, including waxes and similar substances, whereby the composition is provided in the form of a capsule, and, the process is carried out by a machine with functional characteristics specific to the production of candles and meant for a small scale usage. The author has henceforth registered the PT 103856 thereby disclosing several functional aspects of a machine for producing candles based upon the processing of used cooking oils together with a solidifying composition based upon paraffin, stearin, microcrystalline wax, essences, anilines and other stabilizers. According to the document this composition is provided in the form of a capsule of cylindrical format. However, this cylindrical format has revealed itself as disadvantageous in several aspects. Moreover, the document does not disclose any particular technical characteristics neither of the capsule, notably in view of an efficient processing thereof, that is, ensuring a complete mixture with the used cooking oils in the shortest period of time and with the least energy use As described in detail further below, such characteristics play a determinant role in the efficiency of the process and on the quality of the candles obtained as result of it.
- The WO 2010/102370 A1 discloses an apparatus of domestic use for producing soap by means of recycling used cooking oils. This document points to the addition of several compounds separately from each other and in the same form as they may be usually found in the market. In this case, there is not a composition that integrates the different substances in certain proportions as considered as relevant for obtaining the envisage results.
- The documents above do not disclose solutions in terms of the constitution and configuration of a processing pod, in view of maximizing the efficiency of the process and the quality of the candles obtained by it.
- In fact, the production of candles from used cooking oils, as well as other products based upon the use of a wax, or similar, raises several issues. In this sense, as main quality aspects of a resulting candle, one highlights the structural stability at ambient temperature (including during very hot summer days), the uniform visual aspect, the suppression of smells often associated with used oils, the regular and complete burning behavior, and the observation of applicable safety standards and dispositions, in particular.
- The author has carried out several tests and thus established that in order to obtain a quality candle by means of an efficient process, one obtains very different results from using processing pods with different compression degree and configuration, while keeping the same composition.
- For example, it has been experimentally established that the period of time required to reach a complete mixture of the processing pod with used cooking oils, resulted substantially different when using pods with the same composition but different compression degrees, as represented by its bulk density. Sometimes the fusion obtained at the end of the process did not yet present a uniform visual aspect.
- Moreover, it has been established that the mixing process also takes places in a substantially more efficient way if the processing pod presents a higher specific density when compared to the used cooking oils, so that it sinks in such medium. Also in terms of the configuration of the processing pod, it has been established that certain formats lead to a much more efficient mixing process, that is requiring less time for a similar level of energy being used, and better final quality than other formats.
- Moreover, it has been experimentally established that the incorporation of aromatic substances could be significantly increased and its efficacy of action significantly improved, in the case of certain compression degrees of the processing composition. This aspect has a particular relevance due to the need of suppressing unpleasant odors, sometimes very intense, of certain used cooking oils, for example those used in frying, which might otherwise compromise the final quality of the candles.
- The use of a processing pod with a certain compression degree and at least a certain bulk density, according to the invention, thus allows to very significantly reduce the energy needs of the mixing process, so that a processing apparatus of smaller energy requirements may now be used, thus allowing the use of other type of appliances, other than specific for this purpose, or, alternatively, that the processing apparatus may present a substantially bigger processing capacity for the same level of energy capacity.
- Moreover, it has been established that different substances, bearing different contributions to the processing of a used cooking oils load, such as, for example, a mostly structural contribution, or a mostly functional contribution, such as for example aromatic, cosmetic, or other, may be better mixed with the used cooking oils load if provided in different supports. Providing different processing compositions in respectively different supports advantageously allows a greater control over the conditions according to which different compositions are added to the mixing process, and provides the user with the option, over which complimentary elements she wishes to add to the processing of a given load of used cooking oils.
- To this effect, according to an inventive aspect of the present invention, the processing pods present a main structure whose composition is mostly intended for the basic processing of a load of used cooking oils, and, should that be the option, a secondary structure, whose composition is intended for the addition of a complimentary characteristic or functionality, thereby eventually presenting a different embodiment and/or components than the main structures.
- The present invention further refers to an apparatus that may include more than one processing device presenting energy requirements that are substantially similar to those of a common household appliance.
- The apparatus according to the invention may be used for the production at least of the body of candles, or of a surface treatment product, or of a cosmetic product, or other, according to the functional substances included in the main structure and/or secondary structure of the processing pod according to the invention.
- The goal of the present invention is thus to provide a processing pod for use in a valorization process of used cooking oils, by means of an apparatus of household type (that is, not industrial) whether specific, such as for example a used cooking oils recycling device, or available by means of an household appliance, such as for example a gas oven or a microwave oven, that ensure safety conditions in terms of thermal protection and confinement of the space in which the process takes place, with the least possible energy consumption.
- This goal is solved according to the invention by means of a processing pod according to the first characteristic identified hereunder. Preferred embodiments of the processing pod according to the invention result from the other characteristics presented thereafter.
- Another goal of the present invention is to identify the main characteristics of an apparatus of the type household appliance, for recycling used cooking oils in a domestic setting, by means of their processing together with at least one processing pod according to the invention.
- This goal is solved according to the invention by means of an apparatus according to a first respective characteristic presented hereunder, and allowing the use, under the identified conditions, of household appliances such as for example gas oven, or, preferentially, microwave oven.

FIGS. 8 a-8 b: schematic representations, of a first and second embodiments, respectively, of a machine (2) according to the invention, for processing used cooking oils. - The author has previously disclosed the possibility of recycling used cooking oils by means of their processing together with a solidifying composition. However, in practice such a process raises several difficulties in view of the process efficiency and quality of the product obtained, notably because of the widely varying nature of used cooking oils and of the comparatively high load of inconvenient compounds present in the used cooking oils, some of which being of difficult suppression. For example, in the case of frying oils, these often carry an unpleasant odor.
- According to experiments carried out by the author, it has been established that processing a mixture of used cooking oils with a corresponding solidifying composition takes place in significantly more advantageous conditions, in terms of energy efficiency of the process and degree of homogeneity of the resulting fusion, when the solidifying composition is provided in the form of a processing pod (1) with certain constitution and configuration characteristics. Thus, as a first inventive aspect according to the present invention, it has been established that the efficiency of the mixing process is substantially increased in case the processing pod presents lower compression degree, that is, a lower apparent density than its reference component. As a complementary aspect, it has been established that pods with a higher surface to volume ratio could also be processed more efficiently.
- According to another inventive aspect, the main structure (3) of a processing pod (1) according to the invention, results from a previous processing, preferentially carried out on the factory side, by means of melting a plurality of substances, and, in a particularly advantageous way, presents a compression degree that is inferior to the one that it would present in case of direct pouring or injection of a resulting fusion into a respective mold. For the type of components considered for the main structure (3), including a substance (A) corresponding to a wax, or similar, it thus results as particularly advantageous, when the main structure (3) presents a bulk density that is at least 10% inferior, preferentially at least 15% inferior, more preferentially at least 20% inferior, to the reference density of the substance (A).
- This embodiment presents several advantages, notably in terms of the required processing energy and homogenization degree attained in a mixing process of the processing pod (1) with a load of used cooking oils. In fact, the author has experimentally determined that there is a particularly significant difference between pods that are obtained by means of direct pouring or injection of the fusion of its components, typically with higher densities, in comparison with processing pods (1) that present a lower compression degree.
- According to another inventive aspect, at least the main structure (3) of the processing pod (1) presents a configuration corresponding to a high ratio of outside surface relatively to a certain volume, whereby this ratio is, according to the invention, bigger than the one of a regular cylinder of equivalent height for a given reference volume.
-
FIGS. 1 a-1 c, 2 a-2 c, 3 a-3 e, 4 a-4 e, represent examples of such a main structure (3) of the pod according to the invention. -
FIGS. 1 a-1 c, 2 a-2 c represent a particularly simple case, of a main structure (3) with the shape of a ring or of a torus, respectively. -
FIGS. 3 a-3 e, 4 a-4 e, represent an alternative of the main structure (3) in the shape of a star with several points. Naturally, as it will be apparent to the expert in the art, other forms and shapes are possible, that fulfill the same particular aspect of maximizing the outside surface to volume ratio. For example, for illustrative purposes, it would be possible to consider cylinders or spheres provided with a plurality of cavities on their surfaces. -
FIGS. 5 a-5 d represent possibilities of a first use of secondary structures (4) of a processing pod (1) according to the invention, in which the secondary structures (4) are fit-pressed, preferentially by means of a manual fit-press, in respective main structures (3).FIGS. 5 a-5 b thus show a view in perspective of a substantially regular cylinder form. -
FIGS. 5 c-5 d show perspective views of a substantially regular circular ring form. - These may have a configuration basically similar to that of the main structures (3), or may preferentially, be configured as elements with a complementary shape, for the purpose of their engaging connection with a corresponding main structure (3). A first embodiment of secondary structure (4) presents the form of an elongated cylinder (
FIG. 5 a) that may be fitpressed into a respective hole provided in the main structure (3). A second embodiment corresponds to a substantially flat cylindrical ring (FIG. 5 c) that may be fit-pressed onto the exterior contour of a main structure (3) with a substantially cylindrical configuration, for example. The set thus formed allows the user to select, out of a plurality of types of different components, provided in respective secondary structures (4), the one, or the ones that she wishes to add to the solidifying compound provided in the main structure (3), so as to obtain a certain product in view of a certain final use and of a certain particular characteristic thereof. -
FIGS. 6 a-6 f show pairs of respectively plan and side elevation views of three embodiments of the secondary structure (4) presenting a star-like configuration. These secondary structures (4) may be attached side-by-side, by means of additional attaching elements, or directly fit-pressed to main structures (3) that present a hole of similar configuration. - The present invention further refers to an apparatus (2) of domestic use for processing used cooking oils together with a processing pod (1) according to the invention. This apparatus (2) at least includes a processing device (5) for processing a given quantity of used cooking oils together with at least one processing pod (1), so that the used cooking oils and the processing pod (1) are directly delivered to each processing device (5), or are delivered by means of a respective storage recipient (6).
